Shock Block®


Now Available as a Class A GFCI

The Littelfuse Industrial Shock Block is now available as a Class A Ground-Fault Circuit Interrupter (GFCI) with a 6 mA trip level. Now commercial kitchens, construction sites, and other non-dwelling units with wet areas can meet NEC 210.8(B) for their 3-phase loads up to 100 A. This version adds to the existing Shock Block models already available, which offer 20 mA trip levels (Class C and D Special Purpose GFCIs), and selectable trip levels from 6 – 100 mA (EGFPD).
